Background:
In cattle and small ruminants, blood lactate can predict recovery and survival in various diseases. Increased lactate concentration is associated with an unfavourable-to-poor prognosis. Different mobile rapid lactate measurement devices have been explored in different animal species. This study evaluated one device for use in ruminants.
Methods:
Venous blood samples were taken from 111 cattle, 132 sheep, 101 goats and 57 South American camelids, and the StatStrip Xpress Lactate (Nova Biomedical) was used to evaluate lactate concentrations. The RAPIDPoint 500e blood gas analysis system (Siemens Healthineers) was the reference standard.
Results:
There was a strong positive correlation between the two measurement methods (Spearman rank correlation-cattle: r = 0.963, p < 0.001; sheep: r = 0.986, p < 0.001; goats: r = 0.971, p < 0.001; South American camelids: r = 0.852, p > 0.001). The Passing‒Bablok regression showed proportional and systematic differences between the methods.
Limitation:
The number of blood samples from South American camelids was relatively low.
Conclusion:
The StatStrip Xpress Lactate rapid measurement method is a suitable diagnostic tool for safely determining venous blood lactate concentration in cattle, small ruminants and South American camelids.

What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...
01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
